The present invention provides a toner for MICR suitable for use in a printer for a non-magnetic monocomponent developing system, which does not produce scratches on a developing sleeve when used in the printer for the non-magnetic monocomponent developing system and has a resistance against sliding friction with a magnetic head, and also causes no reading errors because of a proper signal strength and imparts satisfactory image characteristics (for example, with respect to image density and fogging). The toner comprises a binder resin, a magnetic material and a wax, and has a BET specific surface area within a range from 0.70 to 1.00 m /g.

Toner for magnetic ink character recognition system and non-magnetic monocomponent development method

A toner for developing electrostatically charged images is disclosed including a binder resin and a coloring agent as principal ingredients, the toner containing ethylene/methyl methacrylate copolymer resin in an amount of 1% by weight to 30% by weight based on the total weight of the toner.
